We look at the division of 55787723 by 663 
The aim is to understand the frequency of 663 in 55787723.

Let's proceed to step 1:
663 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 663

Moving on to step 2:
663 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 663

Advancing to step 3:
The number 663 fits into 557 0 times, leaving a remainder of 557.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 557 to get 557.
Fetch the next digit (8) from the dividend, attach it to 557 and continue: 5578 / 663

Moving on to step 4:
The number 663 fits into 5578 8 times, leaving a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 5304 from 5578, we get 274.
Take the next digit (7) from the dividend and append it to 274, then repeat: 2747 / 663

Advancing to step 5:
663 can be fit into 2747 4 times, resulting in a remainder of 95.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we take 2652 away from 2747, we end up with 95.
Fetch the next digit (7) from the dividend, attach it to 95 and continue: 957 / 663

Advancing to step 6:
When dividing 957 by 663, we get 1 with a remainder of 294.
Record the quotient 1 as the next digit in the result. 
Result so far: 841.0
Subtract 663 from 957 to get 294.
Fetch the next digit (2) from the dividend, attach it to 294 and continue: 2942 / 663

Moving on to step 7:
663 can be fit into 2942 4 times, resulting in a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 8414.0
If we take 2652 away from 2942, we end up with 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 663

On to step 8:
663 can be fit into 2903 4 times, resulting in a remainder of 251.
Put 4 as the next digit of the answer. 
Result so far: 84144.0
If we take 2652 away from 2903, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 9:
663 goes into 2510 3 times with a remainder of 521.
Use 3 as the next digit of our solution. 
Result so far: 84144.3
Subtracting 1989 from 2510 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Advancing to step 10:
The number 663 fits into 5210 7 times, leaving a remainder of 569.
The number 7 becomes the next digit in our result. 
Result so far: 84144.37
If we subtract 4641 from 5210, we get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Step 11:
When dividing 5690 by 663, we get 8 with a remainder of 386.
Write down 8 as next digit of the result. 
Result so far: 84144.378
Deduct 5304 from 5690 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 12:
When dividing 3860 by 663, we get 5 with a remainder of 545.
Use 5 as the next digit of our solution. 
Result so far: 84144.3785
If we take 3315 away from 3860, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 13:
When dividing 5450 by 663, we get 8 with a remainder of 146.
The number 8 becomes the next digit in our result. 
Result so far: 84144.37858
Deduct 5304 from 5450 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 14:
1460 divided by 663 is 2 with a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 84144.378582
Deduct 1326 from 1460 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 15:
The number 663 fits into 1340 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 84144.3785822
Subtract 1326 from 1340 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 84144.3785822 with a balance of 1.4e-07.
